Summary
Aleukemic myeloid sarcoma (MS) can present as skin lesions without blood involvement, posing diagnostic challenges. Early detection and treatment are vital due to the poor prognosis of this rare cancer subtype.
Area of Science:
- Oncology
- Hematology
- Pathology
Background:
- Myeloid sarcoma (MS) is a rare tumor of immature myeloid cells.
- Aleukemic MS is an uncommon subtype presenting primarily in the skin without peripheral blood or bone marrow involvement.
- The non-specific presentation of aleukemic MS can delay diagnosis.
Observation:
- An 83-year-old woman presented with violaceous nodules on her shin.
- A skin biopsy confirmed myeloid sarcoma.
- The patient had no peripheral blood involvement at diagnosis.
Findings:
- The patient was diagnosed with aleukemic myeloid sarcoma.
- Three months later, MS was detected in the common bile duct.
- Bone marrow involvement remained absent throughout the observation period.
Implications:
- This case highlights the diagnostic challenges of aleukemic MS.
- Prompt diagnosis and treatment are critical for improving outcomes in MS.
- MS can present initially in extramedullary sites without hematologic abnormalities.
